INCORPORATION BY REFERENCE

This is a continuation in part application to application Ser. No. 16/017,977 “INTELLIGENT SENSING TOUCH DISPLAY DEVICE” which was filed on Jun. 25, 2018, and which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a touch sensing device, especially to an intelligent touch sensing device.

Description of the Related Art

Please refer to FIG. 1, which illustrates a touch detection scheme of prior art using a plurality of polysilicon thin film transistors and a plurality of capacitive electrodes to form a fingerprint scan matrix on a glass substrate or a polymer substrate. As illustrated in FIG. 1, the polysilicon thin film transistors of the fingerprint scan matrix are sequentially driven to scan each of the capacitive electrodes, thereby deriving fingerprint matrix data.

However, when the fingerprint scan matrix is applied in high resolution or large size products, the scan time thereof will increase substantially due to a much increased number of detection points. Besides, if the fingerprint scan matrix is stacked on a display, the light transmittance rate of the display will be compromised, so generally the fingerprint scan matrix is installed at a zone outside the display (as shown in FIG. 1) for identity authentication via fingerprint detection.

Please refer to FIG. 2, which illustrates another touch detection scheme of prior art using a plurality of common electrodes of a display to form a touch scan matrix. As illustrated in FIG. 2, to wire the touch scan matrix, a large number of conductors and connecting pads have to be installed thereon. When the touch scan matrix is required to possess a high resolution or a large matrix size, the scan time thereof will increase substantially due to a much increased number of detection points, and when the touch scan matrix possesses a high resolution, the pattern of the common electrodes may overlap the pattern of pixel electrodes of the display to result in a moiré effect, thereby degrading the display quality thereof.

That is, when a touch module is required to provide a high resolution touch detection function, the efficiencies of traditional touch detection schemes remain room to be improved, and when a touch display module is required to provide both a high resolution display and a high resolution touch detection function, traditional touch display schemes are hard to achieve both the high resolution touch detection function and the high resolution display quality.

To solve the foregoing problems, a novel touch sensing device is needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 3, which illustrates a block diagram of an intelligent touch sensing device according to an embodiment of the present invention. As illustrated in FIG. 3, the intelligent touch sensing device includes a first electrode group 100, a second electrode group 110, and a touch detection unit 120.

The first electrode group 100 has a first plurality (n) of first electrodes coupled to the touch detection unit 120 via conductive lines T1(1)-T1(n), n being a positive integer.

The second electrode group 110 has a second plurality (m) of second electrodes, each of the second electrodes being under a control of at least one active switch to couple with a touch detection signal transmitted via conductive lines T2(1)-T2(X), X being a positive integer. The active switches are driven by control signals C(1)-C(Y), Y being a positive integer, and the second plurality (m=X*Y) being larger than the first plurality (n). Please refer to FIG. 4a-4f , which illustrates 6 embodiments of the first electrode group and the second electrode group. As illustrated in FIG. 4a-4f , each of the second electrodes of the second electrode group 110 is addressable under the control of at least one active switch.

The touch detection unit 120, coupled with the first electrode group 100 and the second electrode group 110, is used for operating according to an application program to optionally perform a first touch detection procedure on the first electrode group 100, perform a second touch detection procedure on the second electrode group 110, or perform the first detection procedure on the first electrode group 100 and then perform the second touch detection procedure on at least one region of the second electrode group 110, wherein the at least one region is determined according to a detection result of the first touch detection procedure so as to greatly reduce the workload of the touch detection unit 120.

The first electrode group 100 and the second electrode group 110 can be on a same plane or on different planes. Please refer to 5 a-5 b, which illustrates respectively a scenario that the first electrode group 100 and the second electrode group 110 are on different planes and a scenario that the first electrode group 100 and the second electrode group 110 are on a same plane. Besides, the first electrode and the second electrode can be of a rectangular shape or a comb shape.

The first touch detection procedure can be a first acoustic wave type touch detection procedure or a first capacitive type touch detection procedure or a first electromagnetic induction type touch detection procedure, and the second touch detection procedure can be a second acoustic wave type touch detection procedure or a second capacitive type touch detection procedure or a second electromagnetic induction type touch detection procedure. Please refer to FIG. 6a-6j , which illustrates scenarios that the first electrode group 100 and the second electrode group 110 use capacitive type touch detection procedure or electromagnetic induction type touch detection procedure or acoustic wave type touch detection procedure for touch detection, the capacitive type touch detection procedure can be an induced capacitive type touch detection procedure or a projected capacitive type touch detection procedure. As illustrated in FIG. 6a-6j , the present invention can provide single-side touch operation or double-sides touch operation, and the first electrode group 100 and the second electrode group 110 can have a same touch detection scheme or different touch detection schemes.

The touch detection unit 120 outputs data D_(OUT), which can include first touch sensed data of the first electrode group 100 and/or second touch sensed data of the second electrode group 110, and/or fusion data of the first touch sensed data and the second touch sensed data.

The fusion data can be formed with the first touch sensed data having a first bit number per data for representing a first grayscale resolution and the second touch sensed data having a second bit number per data for representing a second grayscale resolution, wherein the first bit number is larger than the second bit number, so that the fusion data can provide enough sensed touch information with a minimum total bit number. As the first touch sensed data are derived from the first electrode group 100, the second touch sensed data are derived from the second electrode group 110, the quantity of the first touch sensed data is smaller than the quantity of the second touch sensed data, and by making the second bit number per data smaller than the first bit number per data, the total bit number for representing the fusion data can be greatly reduced. For example, if the first electrode group 100 has 20 said first electrodes and the first touch sensed data have 8 bits per data representing 256 gray scales, and the second electrode group 110 has 1000 said second electrodes and the second touch sensed data have 1 bit per data representing 2 gray scales, then the total bit number of all the first touch sensed data and all the second touch sensed data will be equal to 8×20+1×1000=1160, and the fusion data derived by performing a fusion operation on the first touch sensed data and the second touch sensed data can provide an effect of a high resolution or large gray levels substantially equivalent to the effect of 1000 8-bit data. On the other hand, although directly using 8-bit (256 gray levels) per data to represent the second touch sensed data can provide more detailed touch sensed information, however, the total bit count thereof will be 8×1000=8000, much larger than the total bit count (1160) required of the present invention.

The first touch sensed data and the second touch sensed data can both be touch coordinate data, or the first touch sensed data be touch coordinate data and the second touch sensed data be raw data of sensed values that are generated without going through a touch coordinate determining procedure (the raw data of sensed values can be digital data derived from a conversion operation on an analog sensed value of a touch sensing point, and a signal processing operation including a filtering operation and/or a gain adjustment operation can be included or not included in the conversion operation), or both the first touch sensed data and the second touch sensed data are raw data of sensed values that are generated without going through a touch coordinate determining procedure, or both the first touch sensed data and the second touch sensed data are processed data of the raw data of sensed values.

The application program can be a fingerprint detection program, and the touch detection unit 120 generates fingerprint data after executing the fingerprint detection program, wherein, the fingerprint data can be raw data derived after the touch detection unit 120 executes the first touch detection procedure and the second touch detection procedure, the raw data being not coordinate data generated by a touch coordinate determining procedure; or the fingerprint data be processed data derived after the touch detection unit 120 executes the first touch detection procedure, the second touch detection procedure, and a fingerprint characteristics retrieving procedure.

The application program can also be a pressure detection program, which is capable of generating pressure value data and/or pressure vector data according to a size of touched area or a total sensed value calculated from raw data of sensed values derived after performing the first touch detection procedure and the second touch detection procedure, the raw data being generated without going through a touch coordinate determining procedure.

The touch detection unit 120 can generate pressure value data and/or coordinate data according to a detection result of the first touch detection procedure, and generate fingerprint data and/or fingerprint characteristics data according to a detection result of the second touch detection procedure; or generate coordinate data according to a detection result of the first touch detection procedure, and generate fingerprint characteristics data and/or pressure value data according to a detection result of the second touch detection procedure.

Please refer to FIG. 7, which illustrates a block diagram of an intelligent touch sensing device according to another embodiment of the present invention. As illustrated in FIG. 7, the intelligent touch sensing device includes a first electrode group 200, an active matrix unit 210, a display material layer 220, a touch detection unit 230, a connection circuit 240, and a display driving unit 250.
